Abstract
Systems and methods for in-service optical fault isolation on a link between a first node and a second node include transmitting counters between each of the first node and the second node; determining associated values for the counters responsive to an event associated with the link; and determining a location of the event based on the associated values for the counters. The determining includes converting time differences between the counters into distance, based on propagation speed of a signal over optical fiber forming the link. The location is determined in-service based on a single occurrence of the event without external equipment.
